OS X Yosemite: How to Find Non-Apple Extensions Lingering in Your Mac – The Mac Observer
"In a terminal window, the following command will show you all the kernel extensions that are active. (The terminal app is found in /Applications/Utilities.)
kextstat -l

There will be lot from Apple, and those are all okay. If you want to see non-Apple extensions, you can pipe the list to the "grep -v" command. The -v option says, "show everything but those items that contain the string that follows." For example:
kextstat -l | grep -v

If you want to write that list out to a text file for examination, enter, for example,
kextstat -l | grep -v > NonAppleKext.txt

Why Github can't host the Linux Kernel Community
The problem is that github doesn’t support the way the linux kernel scales out to a huge number of contributors, and therefore we can’t simply move, not even just a few subsystems. And this isn’t about just hosting the git data, that part obviously works, but how pull requests, issues and forks work on github.
